To a/ZZ whom, it may concern.- Beit known that l, WILLIAM LOREY, residing in the city `of Philadelphia, State of Pennsylvania,have invented certain new and use-' ful Improvements in Filters, of which the followingis a specification.

The primary object of my invention is to produce a filter of increased capacity with ready facility for removing the impure matterv separated from the water and cleaning the filter.V f i In the accompanying drawings, Figure lis a vertical sectional view illustrating the prin-` ciple of my invention. Fig. 2 is a horizontal. sectional view of the construction illustrated in Fig. 1, taken on the line a a thereof. Fig. 3 is a vertical sectional View of a simplified form of my invention, showing a modification in t-he mode of supplying water thereto.

Fig. 8 is a partialfsectional View showing a d'etail of the base' of 1 the a central cylinder and the passages therefor. Fig. 9' is a plan view, partially in section, illustrating the worm-gear for revolving'the ltenj Fig. 10 is a planview, and Fig-11 isa verti, cal elevation illustrating a form of device for. scouring the filter. v

Referring to Figs. 1 and 2 the frame 1 is supported upon a shaft ,2,^jouri naled in a bearing 3 of a bracket 1A gearf, Wheel 5 is fixed on the bracket and engages with a second gear-wheel 6, fixed to the outer end of a shaft 7, journaled in the frame and having a bevel-gear wheel 8 fixed on the inner end thereof. The V'gear-Wheel' 8 engages with agear-track, secured to the base 10 of the filter-casing 11. The casing l1 is fixed upon a shaft l12, journaled in the frame 1. The shaft 12 is cored out -to provide the conduit 13, leading to the chamber 14 in the base of the drawings,:

ofthe casing, which chamber communicates with two sets of tubes 15. The tubes 15 are provided with apertures 16, above which they are closed, forming passages to the chambers 17 located between the concentric cylindrical diaphragms 18, of stone or other suitable porous filtering material. The cylinders 18 are supported upon-the seats 19 and are covered by the caps 20, which close the chambers 17. The cylinders are wrapped with wire 21 to strengthem them or are otherwise suitably sustained. A second set of tubes 22, having apertures 23 in their upper ends, are located -in the chambers 17 and communicate with a chamber 24, having-an outlet25, controlled by a cock 26. The chambers 27, 28, and 29, having the apertures 29', communicate with an outlet 30. Water flows through the channel 13 into the chamber 14, passing thence through the tubes 15 and passages 16 into the chambers 17. It then passes through the cylindrical stones 18 into the chambers 27, 28, and 29,'from which it is drawn off through the outlet 30. The impurities rising to the tops of the chambers 17 pass off through the vapertures 23, the tubes 22, the chamber 24,

and the outlet 25. To clear the lter of deposits of impure matter, a flexible fabric 32, formed as by hinging together sections 32', made of metal or other material having a roughened surface, is placed in the chambers 17, whose walls are scoured thereby by oscillating the filter. The chain or hinged fabric may be replaced bypebbles or any other suitable scouring de vice. To oscillate the filter, the handle of the frame 1 is grasped and the filter is turned about its horizontal axis. The

fixed gear-wheel 5then revolves or oscillates 'the gear-Wheels 6 and 8, causing the filter to turn uponfits vertical axis. The scouring devices arethuscaused to rub the Walls of the chambers in which they are located, thus cleansing the ilter.

' Referring to Fig. 3 of the drawings, the principle of my invention is here applied to a construction in which the frame l', having a shaft 2', journaled in a bearing 3', is provided with a conduit 4', leading to the conduit 13', formed in the shaft 12', which is journaled in the frame and has arms 6' fixed thereon, which strike against a fixed arm 7 when the IOO frame is revolved on its horizontal axis, thus causing the vertical axis and the filtering apparatus supported thereby to revolve. A screw-plug 5' closes the bottom of the conduit 13 and locks the frame to the shaft l2', so that their conduits may be held in registration. lVater fiows through the conduits 4 and 13 into the chamber 14', thence through the tubes l5' and apertures 16 into a single chamber between the stones 18'. From the chamber between the stones 18' the water filters through these stones and passes off through the outlet 30'. The lighter impurities in the water contained in the chamber between the stones 18' rise to the top of the water which fills the chamber and circulating in the channel 8' at the top of the chamber escape through the passage 23' in the tube 22', which communicates with the channel S'. To clean the filter, the plug 5' is removed and the frame is turned upon its horizontal axis. As the frame revolves, the radiating arms G strike the fixed arm 7', thus revolving the filter upon its vertical axis and scouring the walls, as previously described.

Referring to Figs. 4 to 9, inclusive, illustrating the principle applied to a compound construction, the frame 4l is supported upon the shafts 42, journaled in the bearings 43 of the columns 44. A gear-wheel 45 is fixed upon one of the columns and engages with a second gear-wheel 46, fixed to the outer end of a shaft 47, which is journaled in the frame and has a bevel gear-wheel 48 fixed on the inner end thereof. The gear-wheel 48 engages With a second gear-Wheel 48', fixed to a shaft 47', which is journaled in the bearing 41', supported by the frame 4l. A worm 49 on the shaft 47' engages with a rack 49', secured to the casing 51. (See Fig. 9.) The casing is fixed to the shaft 52, which isjournaled in the frame. A number of separate filters are formed by arranging concentric diaphragms 59 about the shaft 52 and the shafts 59'. The shaft 52 is cored out to form the conduit 53,communicating with the chambers or channels 54. Passages lead from the channels 54 to the chambers 56. The chambers 5G' communicate by the tubes 5G and the apertures 57 therein with the channels '58 between the respective pairs of concentric cylindrical stones 59, through which n water filters into the chambers G0, escaping thence through the apertures Gl and passages 62 to an outlet or outlets 63. The impure mattei' passes off through a second set of tubes 64, with apertures 65 at the tops thereof, within the channels 58. The lower ends of these tubes extendinto chambers 6G, connected by conduits 67, through which the impurities pass to the escape-passages 68.

In constructing my filter I prefer to employ the form of cap illustrated in Figs. 3 and 6, in which channels 8' and 58' are formed in the caps, and the respective apertures 23' and 65 are located therein. By this arrangement the impurities may rise above the surfaces of the stones, thus reducing the deposits that tend to form thereon, which obstruct the filtering operations.

Having described my invention, I claiml. In a filter, a revoluble frame, a casing revoluble within said frame, a pair of concentric diaphragms within said casing,a chamber between said diaphragms, a passage for conducting water to said chamber, and a passage for conducting impurities from said chamber, substantially as specified.
